When gas molecules collide, the collision is considered to be an elastic collision. In an elastic collision, both momentum and kinetic energy are conserved, meaning that the total energy before and after the collision remains constant. This behavior is a fundamental characteristic of ideal gas behavior, where interactions between molecules are minimal and only occur during collisions.

What two requirements for the reaction of gas molecules are identified hy collision theory?
Collision theory identifies two key requirements for gas molecules to react: first, the molecules must collide with sufficient energy to overcome the activation energy barrier; second, the molecules must collide with the correct orientation to favor the formation of products. These factors ensure that the collisions lead to effective reactions rather than just ineffective encounters.
Why is a heated gas more viscous than a cooled gas?
Heating a gas increases its kinetic energy, causing its molecules to move faster and collide more frequently. This increased collision frequency leads to greater internal friction and higher viscosity in the gas. Cooling a gas has the opposite effect, reducing molecular motion and collision frequency, thus lowering its viscosity.
What happens when the pressure of a gas is lowered?
The molecules collide less frequently, which normally coincides with a decrease in temperature.
How do you calculate the collision rate of a molecule in a maxwellian gas?
The collision rate of a molecule in a Maxwellian gas can be calculated using the formula: collision rate = n * σ * v, where n is the number density of gas molecules, σ is the collision cross-section, and v is the average velocity of the molecules. The collision rate represents the number of collisions per unit time experienced by a single molecule in the gas.
What is pressure of gas due to?
collision of air molecules with the walls of the container
Why is the collision of gas molecule elastic?
Gas molecules are considered to collide elastically because during collisions, there is no net loss of kinetic energy. This means that the total kinetic energy of the molecules before the collision is equal to the total kinetic energy after the collision. Therefore, no energy is lost in the form of heat or deformation during the collision.
What are gas molecules colliding with no change in total energy?
When gas molecules collide without a change in total energy, it means that the collisions are elastic. In an elastic collision, the kinetic energy of the gas molecules before and after the collision remains constant. This type of collision conserves energy and momentum.

What does the constant collision of gas molecules against the inside walls of a container produce A Temperature Bdensity C Pressure Ddiffusion?
C. Pressure. The constant collision of gas molecules against the inside walls of a container produces pressure. This pressure is a result of the force exerted by the molecules as they collide with the walls of the container.
How does gas create pressure?
Gas molecules collide with the container walls.
Why is a heated gas more viscous than a cooled gas?
Heating a gas increases its kinetic energy, causing its molecules to move faster and collide more frequently. This increased collision frequency leads to greater internal friction and higher viscosity in the gas. Cooling a gas has the opposite effect, reducing molecular motion and collision frequency, thus lowering its viscosity.
What is the behaviour of gas molecules based on the kinetic theory?
Gas molecules are in continuous random motion and they collide with each other.
What happens when the pressure of a gas is lowered?
The molecules collide less frequently, which normally coincides with a decrease in temperature.
Do molecules from gases collide frequently?
Yes, molecules in gases move rapidly and collide frequently due to the high-energy environment of gas particles. These collisions contribute to the overall pressure and volume of the gas system.

The collision rate of a molecule in a Maxwellian gas can be calculated using the formula: collision rate = n * σ * v, where n is the number density of gas molecules, σ is the collision cross-section, and v is the average velocity of the molecules.
